The Court does not have to address whether the 2nd Amendment restricts what the individual states can and cannot do in the way of firearms restrictions and regulations. However, the analysis I've seen indicates that it is likely to try and announce that 2nd Amendment rights are covered by the 14th Amendment, so the same standard will apply to the states. if and how they do this is going to affect the challenges that the states laws face, and it would be no big surprise if the Court told the Circuits and Districts, this is what we will do. Otherwise, they are inviting that as the next case, soon. it seems the Court doesn't want another 2nd Amendment case soon.
